' Application filed January 16,1906. Serial No. 296,271.

To aZZ whom it may concern:

Be it known that I, HARLIE OGDEN Pu'r'r, a

citizen of the United States, and a resident of Millbury, in the county of Wood and State of Ohio, have invented a new and Improved Telegraph-Transmitter, of which the following is afull, clear, and exact description.

M invention relates to a machine for transmitting by telegraph; and the principal ob-' cations which have heretofore been thought necessary in order to transmit characters by telegraph by the operation of a keyboard. With this object in view I have provided a series of key-stems located in such position that they will normally rest directly under the keys or key-levers of a type-writing machine constructed in the usual manner and be ready to be moved into operative position when the keys are depressed in writing, so

that a type-written copy of the message can be produced simultaneously with transmission thereof by telegraph. The construction is such as. to allow a free unrestricted down ward movement of each key-stem, the transmission being accomplished automatically when the key-stems are released and allowed to rise.

It will be understood that the construction of the machine is somewhat modified accord ing to whether it is to be applied to a typewriter of the Remington'type, having one keyboard and a shift-key, or to one of the Smith Premier type, having a double keyboard, or to be'usedindependently of a typewriter.

.Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all figures.

Figure 1 represents in vertical sectional view a portion of a machine constructed in accordance with the principle of my invention and applied to a type-writing machine of the Remington type, having a shift-key. Fig. 2 is a side elevation of a portion of oneof the ke stems and Fi 3 is a sectional view on 7 the line 3 3 of Fig.1.

i have shown the device as applied to a type-writer 10, having key-levers 11 and a. shift-key lever 12. The machine is provided with a supporting-frame 13, which carries a series of bushings 14, passing through openings 15 in the frame and secured thereto by nuts 16 on one side thereof. Passing through each bushing is a key-stem 17, which is supported by a spring 18 in such position that its head 19 rests directly under one of the key- 6 5 levers in such a manner that it follows the motions of the key-lever, being forced upward into contact with it when the key-lever is in a raised position by means of the spring 18. Connected through the bottom of the bushing 14 is a'spring 20, which engages a sleeve 21, that is capable of a slight rotary or oscillating motion thereon. The tendency of the spring is to keep the sleeve or. cam in a certain position, and the bushing is provided 7 5 with a pair of pins 22, projectin through slots 23 in the sleeve and limiting t .e motion thereof; The lower end of the sleeve is provided with a pair of inclined surfaces 24 and 25 on each side. surface 25 is a strai ht surface extending toward one side of the ey-stem 17 from the center, while the surface 24 is curved. There I are two of each of these surfaces in the present instance.

to a point adjacent to the upper end of the other surface 25. These surtaces constitute cams for operating a cross-bar 26, which is fixed to the key-stem 17 to provide for turn-. 0

ing the latter. It will be observed that when the key-stein is forced downwardly by the operation of one of the key-levers of the typewriting machine the cross bar 26 will be forced from theposition shown in Fig. l 5 and 2 downwardly along the inclines 25,:

which give it a slight turn in one direction until it reaches" the bottom of this incline and slips' oyerthe end of the surface 24:. When the .keydever israised and the spring 18 100 forces the cross bar 26 upwardly, the camsurfaces 24 will force the stem to rotate. The purposeof this rotation will now be described.

Movably mounted on the lower portion of the key-stem is a sleeve 27, which is provided I o 5 with a pin 28, entering a keyway 29 in the key-stem, so that while the reciprocating motions of the key are not transmitted to the sleeve the rotary motion thereof is. This sleeve is provided with two disks 30 and 31. I To which are composed in the main of conducting material, but are provided with msulat- It will be noticed that the 80,

Each of the surfaces Z i extends upwardly from the lower end of a surface 25 ing-blocks 32 on their surfaces, separated by projections 33' from the conducting material ofthe disk. The operation of these disks to transmit electrical impulses is well understood, the relative positions and sizes of the portions 32 and 33 determining the character which is to be transmitted. In the present case each disk is provided with two charac ters on opposite sides and with two brushes 34. Insulating-strips 35 are located at the ends of the characters, so as to provide for allow-ing the brushes to rest at the end of the stroke without conducting current. The disk 31 is provided with brushes 36, similar to the brushes 34. The two disks are separated from each other by a washer 37, and above the upper one is a washer 38; These washers may serve-as bearing-surfaces for "the resilient brushes. Outside the arts so far described is a shell39, of hard rubll er, fiber, or any insulating material, and this is provided for-supporting the brushes which have been described. It will be seen that upon each operation of a key one of the key-stems will be depressed and both of the disks connected therewith will be rotated when the key is released. In order to provide for regulating and making uniform the return motion of the key-stem, and consequently the rotation'of the disks, I have prov-ided a cylinder 40, in which is mounted a piston 41, provided with one or more restricted perforations 42. This piston is mounted on the lower end of the formly, so that the characters can be transkey-stem, and the cylinder is provided with a perforation 43; It will be seen that this prevents the immediate return of the key-stem, but permitsit to return graduallyand uniinitted in a uniform manner.

'It will be observed that in a t -Wri terj having a double bank of keys an .no shift key it will merely be necessary to provide each key-stem with one of the disks whichhave' been described, and my invention contemplates this simplification of the mechanism illustrated in the drawings. When, however, it is desired to ap ly the device to a machine having one ban of keys and a shiftkey, the two disks are employed, both being connected with the brushes'at all times, and I provide means operable by the shift-key for opening the circuit through 'one of the disks at all times, so that only one of the disks can transmit its character, and the character to be transmitted will depend upon the position of the shift-key, it being understood thatfthe character onone of the disks will represent the character printed by the -t pe-writer when the shift-key is in norma position,

while that on the other represents the character printed when the shaft-key is depressed.

For the purpose of makingthese connections locate under the shift-key lever a shift-key stem 44. his stem is provided with a spring 45 and a head 46, similar to the springs 18 and heads 19, and it is also connected with the frame 13 by a bushing 47, similar to the bushing 14, except that it is insulated from the frame by a collar 48. This bushing carries a shell 49,- of insulating material, which is provided with a pair of conducting-rings 50 and 51, separated by an. insulatingcollar 52.

The bottom of the shift-key stem 44 is provided with a spring-53, adapted to bear on the inner surface of the shell and of the con ducting-collar 50 and 51. When the shiftkey is in normal position, the spring 53 'bears on the collar 50 and a current is transmitted from'a line-Wire 54 to a binding-post 55, through the frame of the machine, thence through the-several bushings 14 and keystems 17 .to. the disks 30 and 31, and from them, by means of brushes 34 and 36, to a pair.

machine, and to the other main 60. When the shift-key is depressed, however, the spring 53 isbrought down into engagement with' the collar 51, and therefore connected with the conductor 57 and brushes 36, the ath of the current being the same as before. t will be seen, therefore, that the osition of the shift-key determines which 0 the disks shall transmit its character upon the rotation thereof.
